MINING-DRILL AND CHANNEL-CUTTER.

SPECIFICATION forming part of Letters Patent No. 395,716, dated January8, 1889.

Application led January 25, 1888. Serial No. 261,823. (No model.)

To all 1071/0122, it may concern:

Be it known that I, JOHN PHTLLIP PAYN- TER, of Pomona, in t-he county ofFranklin and State of Kansas, have invented a new and ImprovedMining-'Drill and Channel-Cutter, of which the lfollowing.; is a full,clear, and exact description.

The object of the invention is to provide a new and improved drillespecially adapted in mining coal for uudcrcntti ug the coal in smallseams, so as to relieve the miner from the hardest'and most (liitieultwork, at the same time cheapening the cost of mining'.

The invention consists in certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation of the improvement. Fig. 2 is a sectionalend elevation on the line a; cc of Fig. 23. Fig. 3 is a plan view of theimprovement. Fig. d.. is an enlarged sectional end elevation of thedrillingtool, and Fig. 5 is a side elevation of one of the cutters ofthe drilling-tool- On a suitably-constructed frame, A, are mounted torotate the pulleys B, traveling on longitudinal bars or pipes (l,passing through the said main frame A and being supported at their outerends in bearings fastened on jack-screws D and D', of any approvedconstruction and adapted to be set up in a mining-shaft- On the mainframe A is mounted the steamengiue E, of any approved construction andprovided with a main driving-shaft, F, carrying a sprocket-wheel, F',over which passes the endless sprocketchain F2, also passing over asprocket-wheel, F3, secured to one end of the shaft G, mounted to rotatein suitable bearings on the front end of the main frame A. On theopposite end of the shaft G screws the drilling-tool H, made in theshape of a conical screw and provided with one or more rows of cutters,I, screwing into the thread of the said screw, as shown in Fig. 4.. Eachcutter I is provided on its upper end with a point, I', which cuts intothe coal when the said Screw is rotated.

The drilling-tool Il is provided with a central aperture, H', from whichaperture smaller branch apertures, H2, are formed, which pass throughthe body of the screw and serve to pass air through the drilling-tool H.The cent-ral aperture, H', connects with a similar aperture, G', in theshaft G, and the outer end of said shaft connected by suitable hose withmeans for supplying air.

The inner end of the drilling-tool l-l abuts against the shoulder (l2,formed on the shaft (if, so to prevent said d rilling-tool from screwingtoo hard on the said shaft G. On the latter is formed a worm, J, whichmeshes into a worin-wheel, K, secured on the vertical shaft I., mountedto .rotate in suitable bearings on the main frame A, and on the saidshaft L is secured a bevel gear-wheel, N, which meshes into a pinion, O,secured on the horizontal shaft P, mounted to rotate in suitablebearings on the main lframe A, and carrying a sprocket-wheel, Q, overwhich passes the sprocket-chain R, also passing over a sprocketwheel, S,mounted to rotate on the frame A, and then one end of the chain passesdown to the ground, as shown in Figs. l .and 3. The sprocket chain R,after passing over the sprocketwheel Q, passes over a sprocket wheel orpulley, T, mounted to rotate on one side of the main frame A, and thensaid chain passes forward and is secured by its outer end to ajack-screw, D2, of any approved construction and set up in themining-shaft.

A sidewise motion of the frame A on the longitudinal rod C is preventedby a frictionpulley, B', mounted on a vertical shaft held to rotate onthe main frame A, .as shown in Figs. l and 3. n

The operation is as follows: The machine is specially adapted forundercutting small seams of coal. In order to do this, the jackscrews Dand D' are set up in a mine-shaft into which the seam opens, and thesaid jackscrews support the rods or bars C, on which is held to travel.the main frame A, as above described. The main frame A, with the drill-Thus it will be Soon IOO that the drilling-tool H cuts a narrow openingor slot in the seam or underneath the coal, so that the miner can easilywedge down the coal above. In the beginning the main frame A is near therear jack-screw, D, and one end of the sprocket-chain R is secured tothe jackscrew D2, set up a suitable distance in advance of the machine.Then steam is admitted to the engine E, its main shaftl? is rotated, soas to impart by means of the sprocket-wheels F and I and thesprocketchain F2 a rotary motion to the shaft G, whereby thedrilling-tool Il is rotated, and the cutters I cut with their points Iinto the seam of coal. At the same time the rotation of the shaft Gimparts a rotary motion by means of its worm J, meshing into the worm'-wheel K, to the shaft L, and the latter imparts its rotary motion, bymeans of. the bevel gearavheels N and O, to the shaft P, so that thesprocket-wheel Q is rotated, whereby the main frame A is pulled forwardon. the rod C as the said sprocket-wheel Q takes up the links of thechain R until the shaft G is moved within a short distance of the innerjack-screw, D. The frame A is then raised a short distance on suitableprops, so that the said rods become free and are moved forward, at thesame time shifting the jack-screws D, D', and D2 again, so that the rearjack-screw, D, is near one end of the main frame A, while the otherjack-screws, D and D2, are a su itable distance away from the main frameA, after which the sprocket-chain R is again secured by its outermostlink to the jack-screw The props under the main frame A are thenremoved, so that the entire machine can again travel on the rod C, asabove described.

The air admitted to the shaft G and the drill-tool II keeps the lattercool, and Ain case the cutters I become dull from wear the entire toolHis unscrewed from the shaft G and anew one is inserted. The cuttersIcan easily be sharpened and replaced when entirely worn out.

' Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A mining drilltool consisting of a longitudinally and transversely apertu red conical screw provided withcutters, substantially as described.

2. A mining drill-tool consisting of a conical screw having a centrallongitudinal aperture and a series of transverse apertures leading' fromthe longitudinal aperture and provided with a series of removablecutters secured in the threads of the screw, substantially as hereinshown and described.

3. In a mining-drill, the combination, with a drill-supporting framemounted on wheels or rollers, of jack-screws provided with sidebearings, and rods or bars supported in said bearings and forming atrack for supporting the said frame, substantially as herein shown anddescribed.

4. In a mining-drill, the combination, with a track and a frame mountedon rollers and traveling on said track, of an engine carried by theframe, a transverse cutter-shaft operated from the engine, asprocket-wheel operated from the cutter-shaft, and a sprocketchainhaving one end secured to a support and passing' over the saidsprocket-wheel and `over guide wheels or pulleys, substantially asherein shown and described.

5. In a mining-drill, the combination, with Vfixed rods, of a frameadapted to slide longitudinally on the said rods, an engine located onthe said frame and provided on its main shaft with a sprocket-wheel, ashaft mounted to rotate on the said frame and provided with asprocket-wheel, an endless, sprocket-chain passing over the said twosprocket-wheels, a drilling-tool havin g cutters and screw-threads andsecured on the said shaft, aworm formed on the said shaft, a worm-wheelsecured on a vertical shaft mounted inthe said frame, said worm-wheelmeshing in the said worm and also carrying a bevel gear-wheel, abevel-pin ion meshing in the said bevel gear-wheel, a shaft carrying thesaid "bevel-pinion and mounted to rotate on the said frame,asprocketwheel secured to the said pinion-shaft, and a sprocket-chain passingover the said sprocketwheel and having one end secured on a fixed point,substantially as shown and described.
